IMPROVEMENT IN ALARM-GUNS.

The Schedule referred to in these Letters Patent and making part of thesame To all whom. 'it may concern:

Be it known that I, G. J BEASLEY, of Petersburg, in the county ofDiuwiddie, and State of .Virginia, have invented a new and improvedAlarm-Gun and do hereby declare that the following is a full, clear andexact description thereof, which will enable others skilled in the artto makeand use the same, refer ones being had-tothe accompanying drawingforming part of this specification, in which- Figure 1 represents a sideelevation of my improved alarm-gun.v

Figure 2 is a plan ortop view of the same. Similar letters of referenceindicate corresponding parts.

This invention relates to a new alarm-gun which is so arranged that thebarrel of the gun will also constitute the hammer for firing oh", and sothat the gun will be discharged in the same direction in which thestrings of the alarm apparatus are pulled.

The invention consists chiefly in so prolonging the barrel of the gunnear the muzzle that it can be turned in either direction, and inproviding it. with vents and nipples on opposite sides, so that eitherone will be discharged when brought in violent contact with afi'xedsupport.

' The invention also consists in the general arrange- 1 .ment oftrigger-bar,- springs, 860., as hereinafter more fully described.

A in the drawing represents the supporting-frame of the gun.

It is by a downward-projecting vertical pin, a, swiveled in.asupporting-bed, B, of suitable form, so that said frame A can be freelyturned on the pin a.

The gun O is with its projecting trunnions l) b pivoted in ears 0 thatproject from the frame A.

The trunnions b are near the muzzle end of the gun, and have projectingarms d at their ends.

Springs D which are attached to the frame A fit against the sides of thepolygonal arms at and serve to retain the barrel 0 in averticalposition', and to throw y it into a horizontal position whenever it isin the least displaced. r There are two vents on opposite sides of thebarrel and a nipple .is provided for each vent, as shown. When a cap isplaced on each vent, the gun may be swung in either direction, and will,as it is violently swung horizontally by the action of the springs andthe weight of the breech end, strike one cap against one of two lugs fprojecting from the frame A, thereby exploding the charge.

The barrel thereby also serves as hammer.

The displacement of the gun from the vertical position can be producedby suitable means.

One device for this purpose is shown in the drawing. It consists of asliding bar, E, which has a-notch adapted to receive a lug, 9, thatprojects from one trunnion of the gun. In whatever direction the rod Eis pulled will the lug be drawn, and the muzzle of the gun directedWhile discharging.

The rod may be connected with strings or other devices constituting thealarm apparatus.

Having thus described my invention,

' What I claim as new, and. desire to secure by Letters Patent, is--r 1. An alarm-gun which is provided with double vents and nipples, andso arranged that its barrel will also constitute the hammer,substantially as herein shown and described.

2.. The combination of the notched sliding rod E with the pivoteddouble-vent gun O, springs D D, and

frame A, all arranged and operating substantially as herein shown anddescribed.
